[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities. After the construction process is completed, a large amount of construction waste will be generated, which contains a large amount of metal materials, so the metal materials need to be recycled.

[0003] The prior art publication number is CN217093671 U, which is a construction waste recycling device for construction project management. When in use, the device is crushed by a crushing roller, and a magnetic suction mechanism is set to adsorb the metal part for separation. However, when the device is in use, the waste after crushing is of different sizes, and the metal part and the non-metal part in the larger part are not completely separated, so the metal part cannot be completely recovered. Moreover, when the device is magnetically attracted, the magnetic suction structure has a small adsorption surface and a small single adsorption amount, and the operation needs to be repeated many times, which is inefficient. Moreover, the magnetic suction structure passes over the crushed material and can only adsorb the metal part on the surface, while the metal part below is buried and cannot be adsorbed, resulting in incomplete separation.

A bracket 13 is fixedly connected, and a first motor 11 is fixedly connected to the inner side of the bracket 13, the output shaft of the first motor 11 is fixedly connected to one of the crushing rollers 2, and two gears 9 are movably connected to the other side of the box body 1, and the two gears 9 are respectively fixedly connected to the two crushing rollers 2. A sieve plate 3 is provided in the box body 1, and the sieve plate 3 is located below the crushing roller 2, an adsorption plate 5 is provided below the sieve plate 3, and both ends of the adsorption plate 5 are movably connected to the box body 1, the adsorption plate 5 is hollow, and an electromagnet is fixedly connected inside the adsorption plate 5, a cleaning plate 17 is provided above the adsorption plate 5, and a cleaning outlet is opened on the side of the box body 1.

[0025] According to the overall structure of the device, the waste is poured from the top of the box 1, the first motor 11 is started, and the crushing roller 2 is driven to rotate by the first motor 11 and the two gears 9 to crush the waste. The crushed waste falls on the screen plate 3 and is screened by the screen plate 3. The screened waste falls on the adsorption plate 5, and the metal part in the waste is adsorbed by the electromagnet in the adsorption plate 5, while the non-metal part continues to fall into the collection box 6, and then the electromagnet is turned off, and the metal part is swept out from the sweeping outlet for collection by the cleaning plate 17.

[0026] like Figure 3 , 4 As shown, a U-shaped fixing plate 4 is fixedly connected in the box body 1, a U-shaped slot is opened on the inner wall of the fixing plate 4, the periphery of the sieve plate 3 is inserted in the slot, and the top of the fixing plate 4 is inclined.

[0027] The sieve plate 3 is sealed by the fixing plate 4 to prevent waste from leaking from the gap between the sieve plate 3 and the box body 1. The top of the fixing plate 4 is tilted so that the waste falls on the top of the fixing plate 4 and slides toward the sieve plate 3 to prevent waste from remaining.

[0028] like Figure 3 , 5 As shown, the sieve plate 3 is arranged at an angle, a slot is provided on the right side of the box body 1, the sieve plate 3 extends out from the right side of the slot, a second motor 12 is fixedly connected to the bracket 13, and the output end of the second motor 12 is transmission-connected to the sieve plate 3, a turntable 14 is fixedly connected to the output end of the second motor 12, a connecting rod is fixedly connected to the sieve plate 3, a communicating slide groove is provided on the fixed plate 4 and the box body 1, the connecting rod passes through the slide groove, and a transmission plate 15 is movably connected between the connecting rod and the turntable 14.

[0029] The turntable 14 is driven to rotate by the second motor 12. As the turntable 14 rotates, the turntable 14 drives the transmission plate 15 to deflect, and drives the screen plate 3 to move back and forth through the transmission plate 15 and the connecting rod, thereby shaking the waste above the screen plate 3, strengthening the waste screening, and making the waste that cannot pass through the screen plate 3 slide out of the box 1 from the screen plate 3, so as to facilitate collection and continue to be put into the box 1 for secondary crushing.

[0030] like Figure 3 , 5 As shown, there are several adsorption plates 5, which are all inclined and arranged linearly laterally. A connecting plate 19 is movably connected between the adsorption plates 5, and a first hand wheel 18 fixedly connected to the middle adsorption plate 5 is provided on the outside of the box body 1.

[0032] like Figure 5 As shown, a fixing block is fixedly connected to the cleaning plate 17, a threaded hole is provided on the fixing block, and a screw rod 16 is threadedly connected in the threaded hole. The screw rod 16 is movably connected to the box body 1 and extends to the outside to be fixedly connected to the second hand wheel 10.

[0033] The screw 16 is rotated by the second hand wheel 10 to move the fixed block along the screw 16, thereby driving the cleaning plate 17 to move, and the metal part on the upper surface of the adsorption plate 5 is cleaned out from the cleaning outlet, so as to facilitate the collection of the metal part.

[0034] like Figure 5 As shown, there are three fixing blocks, the screw rod 16 is located on the middle fixing block, through holes are opened on the fixing blocks on both sides, and fixing rods 20 are arranged in the through holes, and the fixing rods 20 are fixedly connected to the box body 1.

[0035] The cleaning plate 17 is supported and limited by the fixing rod 20 to prevent the cleaning plate 17 from deflecting during movement.

[0036] Working principle: When in use, connect the device to an external power source, pour the waste from the top of the box 1, start the first motor 11, and drive the crushing roller 2 to rotate through the first motor 11 and the two gears 9 to crush the waste. The crushed waste falls on the screen plate 3 and is screened by the screen plate 3. At the same time, the second motor 12 drives the turntable 14 to rotate, and drives the transmission plate 15 to deflect, and drives the screen plate 3 to move back and forth through the connecting plate 19, so that the waste that has not passed through the screen plate 3 is shaken off and slides out of the box 1, which is convenient for secondary crushing, and the screened waste falls onto the adsorption plate 5, and the metal part in the waste is adsorbed by the electromagnet in the adsorption plate 5, while the non-metal part continues to fall into the collection box 6, and then the first hand wheel 18 is turned to make the adsorption plate 5 horizontal, the electromagnet is turned off, and the second hand wheel 10 is turned to move the cleaning plate 17 to sweep the metal part out from the sweeping outlet for collection.
